Ice Shot/Barrage Help

looking to start an ice shot character and currently have around 35 exalts to spend. I was wondering what items I should prioritize first. I'm aware of the typical death's opus and hyrri's ire but was wondering what items I should prioritize next specifically to help with barrage single target as ice shot doesn't struggle to clear with very little investment

Best idea would be to ask in this thread: https://www.pathofexile.com/forum/view-thread/2660684
